NASA is closing an important chapter of its history. Jim Green, the chief scientist at NASA, has been with the agency for more than 40 years. He plans to retire early in 2022. His work includes the creation of NASA's equivalent of the internet (the Space Physics Analysis Network), shortly after his arrival in 1980. But, he is best known for leading some of NASA's most important space exploration projects over the past 15 years.
Green was the director of NASA's Planetary Science Division, which was responsible for the Curiosity landing in 2012. He also played a crucial role in explaining the Mars Rover to the public. Green also played a key role in the Juno probe’s investigation of Jupiter, Messenger’s tour of Mercury, Dawn’s visit to Ceres, and New Horizons’ historic flyby Pluto. He also approved plans for the Perseverance Rover, which is currently roaming Mars.
Although it is not clear who will succeed Green at this time, he will help in the search for his successor. It's certain that he will leave a strong legacy. He nurtured and made missions more accessible to the public. This is why Curiosity, New Horizons, and other vehicles were so exciting. Green's work could have been a great inspiration for anyone interested in pursuing a career as a space scientist.
